O.J Simpson has confessed to Oprah Winfrey that he murdered his former wife, it has been reported.

The talk show host made headlines recently saying that one of her regrets was never having got the shamed former sportsman to confess to the killing.

And it appears her wish may well have come true with reports Simpson has already told one of her producers in an interview from jail that he knifed ex-wife Nicole in self-defence – a confession he will now repeat to the talk show queen during a spectacular televised sit down interview.

Revealing all? Oprah is said to be lining up an historic interview with Simpson

Simpson is currently serving a nine-year sentence at Nevada’s Lovelock Correctional Centre, after he was convicted of robbery and kidnapping in Las Vegas in October 2008 after a botched heist to retrieve his memorabilia he said was stolen by dealers.

Coup: Will Oprah finally get the confession from O.J. Simpson that she is said to have been pining for?

He was famously acquitted in October 1995 of the murders of ex-wife Nicole Brown Simpson and her friend Ronald Goldman despite huge amounts of evidence against him.

According to the National Enquirer, the interview is set to be filmed after Simpson confessed he killed the pair in self-defence to a producer from inside prison.

‘Oprah has been in touch with O.J. for the past year,’ a source told the magazine. She contacted him in prison to explore the possibility that he might give her an interview.

‘He has always been a big fan of hers, but for a long time he was reluctant to say he did the crime or give the details of how it happened.’

According to the insider, Simpson recently decided to go through with the confession after he was contacted again by one of Oprah’s producers.

‘He told the producer: “Tell Oprah that yes, I did it. I killed Nicole, but it was in self-defence. She pulled a knife on me and I had to defend myself”,’ the insider was quoted as saying.

He reportedly then went on to give a full account of what happened on the night of the murders on June 12 1994.

Confession? O.J. Simpson and his ex-wife, Nicole Brown Simpson, when they were a couple in 1993

The former couple had got into an argument after Nicole was said to have snubber Simpson when he interrupted a meal she was having at a restaurant with their children.

‘O.J. said he went home and kept getting angrier and angrier and worked himself into an absolute rage,’ the source told the Enquirer.

Simpson allegedly told the producer he ‘didn’t like the way she treated me in front of the kids at the restaurant. I didn’t like that she was routinely having guys have sex with her at her condo with the kids there.

‘I went over there to give her a piece of my mind,’ he was quoted as saying.

When he arrived and no one answered at the house, he started pounding the door and shouting, according to the report.

The door allegedly then swung open and Nicole was standing there with a kitchen knife in her hand.

‘O.J. told the producer, “she was yelling go away! Go away! And waving the knife around at me. At one point she was lunging at me with the knife and I was just trying to talk to her. Nicole stepped out of the apartment – slashing the knife in the air.

‘”I was in such a rage that something just snapped. I couldn’t take her constant taunting of me with other men or her using drugs and drinking while my kids were living with her. I went beserk.

‘”Before I knew what I was doing I took the knife away from Nicole and started slashing at her. I cut her over and over again until she was lifeless. I was shocked at my own anger – I had killed the woman I had loved for so long..”‘

Evidence: A glove that was found at Simpson’s home – originally said to have been the pair to another which was bloodied from the violent murders

Weapon: A German-made 15-inch knife similar to one originally said to have been sold to Simpson five weeks before the murders

He allegedly went on to tell the producer he also knifed Ron Goldman in self-defence as he tried to attack Simpson when he turned up at the home soon after and spotted Nicole’s body on the floor.

The shamed former sportsman was acquitted on October 3, 1995 of stabbing to death his ex-wife Nicole Brown Simpson and her friend Ronald Goldman after perhaps the most famous trial in modern history.

After the bodies were found in a pool of blood on her driveway in Los Angeles driveway, Simpson, who has until now maintained he did not commit the murders, began a bizarre slowspeed car chase with police.

Custody: Simpson’s original mugshot

Almost 100million people are thought to have watched the events live on television as the sports star held a gun to his head while being driven by a friend.

He was allegedly headed for the Mexican border with $5,000 dollars and his passport when he was tracked by authorities.

Eventually, 27 police cars trailed him until he surrendered on his mansion’s driveway an hour and a half later.

Despite huge amounts of evidence against Simpson, including bloodstains in his car, a glove holding DNA from the three, a sockengrained with traces of his victims’ blood on his bedroom carpet and tapes of a terrified Nicole begging police for help as Simpson hit her – he was acquitted of the murders.

If the confession is made to Oprah on television, Simpson will not, however, suffer legal consequences.

Under the law of double jeopardy, a second trial is forbidden following an acquittal.
